NEW YORK CORPGRATION F sPIAiTUS FOB. SETTNG PILES Application file May 22,

This invention relates to apparatus for setting piles.

Piles are often constructed from pipe by driving the pipe in the ground or bed to receive the pile and thereafter iilling' the pipe with concrete. In ordinary practice, piles are driven by means of pile hammers which are operaed either by raising by means of rope or cable and being permitted to fall on i" the pile of its own weight, or by automatic hammers operated by steam or compressed air. These hammer blows cause considerable vibration in many soils and often endanger v adjoining or adjacent structures, the vibra- *9 tion causing cracks or settlement of the same.

This invention has for its salient object to facilitate the driving of piles and to accomplish the operation with a minimum of vibration.

Another object of the invention is to provide apparatus of the type specified, so constructed and arranged that the device is adaptedfor use in driving pipe of different sizes.

Further objects of the invention will appear from the following specification taken in connection with the drawings, which form a part of this application, and in which Fig. l is an elevational view of one form of apparatus constructed in accordance with the invention;

Fig. 2 is an elevational view taken at right angles to Fig. l;

Fig. 3 is a perspective, diagrammatic view illustrating the operation of the pulling cable by means ot which the piles are pulled into the ground; Y

Fig. 4 is a plan view of the block adapted to rest on the top of the pipe to be driven; and

Fig. 5 is an elevational view, partly in section, showing the upper end of a pipe and the block resting thereon.

The invention brieiy described consists ot a method of and apparatus for driving piles, so constructed and arranged that a steady or continuous downward pull is exerted on the pile in addition to the driving action of a pile hammer. The two forces for driving the pile may operate simultaneously or either 1329. Serial No. 365,012.

may be used alone. The apparatus is turther so constructed that the block or member which rests on the upper end of a pipe to be driven is adapted to be used in conjunction with different sizes of pipes.

Further details of the invention will appear from the followingl description.

In the particular form of apparatus illustrated in the drawings, the mechanism for pulling down and driving the piles is carried by a frame consisting of a base l() and an upright frame 11, suitably braced, as by struts l2.

The base 10 is preferably mounted on rollers l5,` which in turn are supported by suitable trame work, such as I-beams 16. The I-beams are mounted on supports 17 of any suitable construction; A cross frame member 18 connects the upper ends ot the upright frame members l1 and a sheave :2O is rotatably mounted in a bracket 21 mounted on the frame member 17.

A block 25 4is slidably mounted between the upright frame members 11 and has rccesses 26 at the two edges thereof to receive the members 1l. The block 25 has formed thereon and depending therefrom.. a plu rality of ledges A, B and G of different sizes. adapted to coact with diii'erent diameters of pipes. The block has a pair of horizontal openings 30 and 31 extending therethrough and in these openings are mounted sheaves 32 and 33.

In lorder to exert a continuous downward pull on the pipe to be driven. a flexible cable has its ends and 41 secured to a suitable` fixed abutment, such as the support 17. and passes around the sheaves 32 and downwardly around a pair of sheaves 42 and 413 which are connected to one ofi the supports 17 and upwardly around a sheave 45. The sheave 45 is carried by ayoke 46 connected to a cable 47 which extends upwardly and around a sheave 48 carried by the cross frame member 18. From the sheave 48 the cable 47 passes to a suitable winch or drum. by means of which force can be exerted thereon.

In order to provide for the use of a pile hammer in conjunction with the continuous downward pull exerted by the cable mechanism above described, a hammer` 5()V of any Vsuitable V*construction is suspended from a Y Ycable 6l which passes upwardly and around La sheave 20.' The cable lrcan be slacked 0E as thepipe :is driven so as Vto bringthe Y hammer'in tocooperative relation withy re-y Y Y spect to theblock 25 on which it operates.
